Most books about global warming - important though the issue is - tend to be a little on the worthy side, and deeply depressing. This book is neither. There are worrying facts, but the verve with which Andrew Simms writes, the stories he includes, as well as the photographs and bizarre illustrations, make this one of the key texts for the debate, and the most readable. It not only deserves to be read - not least for the important introduction to a whole new idea (eco-debt) - but it actually will be.
